TO ALL WHOM IT MAY CONCERN:

Be it known that I, DAVID F. FETTERLoi" New York city, in the county and State of New York, have invented a new and useful Improvement in Bushing for Barrels; and I do hereby declare the following to he a full, clear, and exact description of the same, sufficient to enable one skilled `in the art to which the invention appertaius to vmake use of it, reference beinglhadto the accompanying drawings, which form a part of this specification, and in which my invention is represented by a sectional perspective view of a portion of the bung stave with the bushing applied, the plane of section passing axially through the bushing. This bushing forms a lining for the hung-hole or other holes in casks o r vats; it isdesigned to save the wear and tear of the `staves, and is secured by 'means of barbed' creases ,on the outer periphery of the bush, which catch upon the wood and prevent its removal. The extended plate surrounding thebush may he fastened by rivets or screws to'the staves,

. if desired.

In the drawings, A is the bush, the interior of whichis` to be occupied. by the bung-plug or faucet; the

plate B forms an extended surface around the bush, and the holes 6 therein afford the meaus of fastening the plate to the staves by screws or rivets. Circular grooves aremade around the hush of such shape as to form a barb-shaped, when received in section. The purpose of this shapeis to present an inclined face to the wood as the bush is driven in, but to present a 'lat face to the wood when a power-is exerted to remove the bush, as will be readily understood from the sectional view.

In driving iu the bush the wood will be pressed by thc inclined face c, but after it has reached its proper position the wood will expand into the grooves, and the square face d will catch` upon the wood and render it impossible to'withdraw the plug without tearing out the wood which holds it. Additional security, if desired, may be attained by the screws or rivets g, which pass through the holes b in the plate B.

Having described my invention, what I claim as new, and vdesire to secure by Letters Patent, is

The bush constructed with the angular ridges presenting an inclined orwedge-shaped surface to the wood, whilethefbush is being driven into place, and a flat surface opposed to the wood when a power is exerted to withdraw the bush, substantially as described and represented.
